Be it known that I, PHILIP HAAs, citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Imrovements in Water-Closets; and I do herey declare the followin and exact description 0 the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

My invention consists in the'novel features Referring to the said drawings,Figure 1.

represents a pers ective view of a closet bowl and flush valve t erefor having my invention embodied therein. Fig. 2. is a vertical sectional view of the flush valve, and adjacent parts of the bowl. Fig. 3 is a bottom lan view of the upper part of the casing o the flush valve. 1g. 4 is a bottom plan view 'of the diaphragm valve,

Fig. 7 is a similar view show lng another slight modification of the invention. Fig. 8 s a vertical sectional view of'a valve mechanism similar to that shown in Figs. 1 to 5 inclusive, constructed entirely separate from the closet bowl.

Referring to the formof the invention.

shown in Figs. 1 to 5 inclusive, A represents the closetbowl of porcelain or earthenware, and of any desired internal construction. The bowl A is side with a hollow boss A formed integrally therewith provided with horizontal to and bottom faces and communicating wit the Water passage or passages of the bowl an The boss A" is its upper face, and an annular recess a surroundmg the said aperture, and the bottom face of said boss is provided with a smaller aperture o The recess a is occupied by a rubber packing ring C upon which rests a circular 'iiietal body forming part of a valve casmg and which for convenience, I term the to be a full, clear,

following description-- detached. Fig. 5 is a top lan view of the lower lpart of the valve provided preferably at one t erethrough and being provided at its lower end with an exterior threaded portion 5 and the interior of said extension, at its lower end is provided 'with a packing recess b and an inwardly projecting annular shoulder orstop 6 above the same. The aperture formed between the valve seat b and the web 1) forms a discharge passage, permitting when the main body B. This main body B is provided main valve is open, 'the'flow of water from of the boss, and thence to the bowl, as will be readilyunderstood.

C represents a" packing ring or gasket,

preferably of rubber, surrounding the lower the inlet pipe therethrough, into the interior end of the extension b and having an ex-' terior conical face engaging the a erture a in the boss A. c is a metal was er below saidrin C, and c is a nut screwed on the threads portion of the extension and clamping the boss A between it and the main body B, of the valve mechanism, thus compressing the packing rings C and C, and

; making a water tight joint between the valve mechanism and the boss A as will be readily understood.

D is a; telescoping water inlet pipe which extends up ,from the floor, and has a portion provided with a plurality of annular recesses extending u into the lower end of the extension 6' within the annular shoulder b. A, packing ring orsleeve (1 of'rubber surrounds said recessed portion of the pipe D and lies in the packing recess b; a metal ring (1 surrounds said pipe D and extends partly into said recess b", so as to engage the packing ring 11" and a, nutd, engages the threaded lower end of the extension 6 and" forces the ring (I up against-the packing ringd' thus expanding it laterally into one or more of the annular rooves d, and making a tight joint, whi e allowing the pipe D to be adjusted vertically in the ex-' -and a threaded portion at its lower end.

e represents a metal disk having a central aperture through which-the sleeve e passes, and providedwith an .annular recess in its lower face which receives a washer e, of a size to engage the valve seat bi, and the said the diaphragm engage the web-b. The web washer and disk are rigidly secured to, the diaphragm by a nut and washer engaging the threaded end of the sleeve e, theparts hein so arran ed that the valve seats itself on t e seat b efore the lateral portions of 11, however, serves to prevent the diaphragm from being sub'ected to strain and mu remagm when pressure is apr'orce said dia be same, after the valve is plied above t seated. I

F represents the upper-portion or casing cap of the valve mechanism, which fits down 11 on the marginal portions of the diaphragm and is secured to the main body B by screws around the edges of the parts, as shown in therein button, and a spring relief valve closed.

. the

1, so as to firmly hold the diaphragm y with a back pressure chamber f, above the diaphragm an having a relief aperture provided with a valve seat held in place y a screw ring f fitting a t readed recess in the up er part of the cap.

Above the re ef a erture, the cap,is provided witha recess the walls of which are exteriorly threaded.

f represents the relief valve which engages the seat f and has an upwardlyextending stem, secured to a push button f '(ordinaril operated manually) which extends through an aperture in a cap f, said cap f bein screwed on the exteriorly threaded recessed ortion of the casing ca The cap f also olds in lace a flexi le' diaphragm f through w oh the stern of the valve passes, to prevent leakage of water around the push 8 normally holds'the he recess communieates with a by-passf which is in communication with an a erture b in the main body B,.and this esta lishes communication with interior of the boss A which forms the discharge chamber or assage of the valve mechanism. The diap agm E is provided rvlth an ofiset'c having an aperture 6 therein which registers with the passages f and b,-when "the parts are in provide means for adjusta ly limiting the opening movement ofqthe main diaphragm this recess is located a packing ring in'place. The said cap is provided mtenor ppsltlon. I also valve which is so constructed as to be capable oi adjustment from the outside Without interfering with the operation of the valve mechanism. This consists in the present instance of a movable plate or blade G, secured to the inside of the casing cap F, as by means of a screw g loosely passmg throu h an aperture'in one end of the late or bla e, the said plate or blade having its other end engaging or in position to engage the main valve, and preferably a portion of the sleeve.

The casing cap F is provided on the outside with an interiorly threaded recess f having a central aperture in its bottom. In h which is held in place and compressed by an internally and externally threaded sleeve H.

h represents an adjusting screw which engages the internalthreads of the sleeve H, an has a stem h passing through the packing ri or washer h to a point adjacent to the bla e G. The sleeve H is also preferabl rovidedat its outer end with a screw plug 3 For closing the end of the sleeve, but this is not essential. v

It will be seen that by) removing the plug h a screw driver may e inserte into the sleeve H, so as to engage the adjustable screw or stop h, and turn it in either direction so as to adpust the position at which the main valve wil be arrested by the engagement of the blade G with said stop. The adjustable screw h is so constructed that it may be screwed in far enoug blade G and force it firmly Into engagement with the main valve when the latter is in closed osition so as tion when it may be desired. Thus in shipping the valve mechanism the screw'h may e screwed in tightly, so as to hold the main valve seated an prevent jarring of the parts, and when a closet is installed and for any h to engage the to hold it in closed posireason it is desired to put it out of operation,

the screw h mav be screwed in so as to hold the main valve mly in its seat and prevent the operation of the apparatus.

I represents a controlling stem which passes through the central aperture in the sleeve 0 of the -main valve with what is termed an easy fit, the annular s ace or vent passage surrounding said stem orming the only communication between the inlet passage, and the back ressure chamber. .his stem is mounted in ependently of the valve, and in this instance is secured to a bracket i cast integrally with the part b which forms the inlet passage.

.When the apparatus hereinbefore described is in operative condition, the diaphragm valve Wlll be held closed by the pressure of water in the back ressure chamber f. To cause a flush of the c oset the operator resses on the push button] to open the reef valve, and releases the push button. At

the instant the relief valve is opened a cerseries tain amount of water escapes from the back pressure chamber f, through they by-pass f into the dischargp chamber in the boss A,- e diaphragmyal've to openand t e flush water. then passes from the pipe thus ermitting t D, extension I) and .the water inlet passage 1) over valve seat b beneath the web I), and to the discharge chamber in the boss A, from which it passes through a suitable dischar epassage indicated at A to the bowl. Whi e t e flushing operation proceeds, a part of the incoming water will find its way through c the restricted annular vent passage around the stem I to theback pressure chamber where its'accumula'tion will, act on the outer side of the diaphragm, to close the main valve 'upon its seat. v

In Fig 8 I have shown a slightly modified form of the valve mechanism hereinbefore described, constructed entirely independently of the closet bowl and adapted tobe connected thereto by suitable pipe connections. .As shown in this figure the main I body, here lettered B, consists of a hollow 5 casing, provided with an annular web 6 and having within said body a discharge chamber b communicating with a discharge passage b, which may be connected to the closet bowl in any desired'way.

B represents a tubular part forming the water inlet passageywhich is screwed into a threaded aperture into the main body, and preferably 1s rovided on its inner end with an integral va ve seatb}. In order tornew the valve seat in case of wear the tubular part B may be removed and a new part inse'rted. The art B is provided with threads for the attac ment to a water supply pipe and. 1t is also provided with an internal pro- JGCUOD. z carrying the controlling stem I. All the remainlng parts of the valve mechanism are constructed identically as shown and described with reference to Figs. 1 to 5- incluslve, and need not be again. described.

In Fig. 6 I have shown a slightly modified form of the valve mechanism, which I find it,

convenientto use in some instances and partlcularly, where it is desired to have the valve mechanism operated automatically by the closet seat. the closet seat and A represents the rim of the bowl, the seat Sbeing provided with an .arm 8, or other suitable .devrce, for engaging 5 The upper end of the sleeve of the main In this figure S representsv the push button, here designated f", of the valve is provided with a valve seat e surrounding the central aperture in said'sleeve, and co-acting with the auxiliary valve 3. The other parts of the valve are constructed exactly as shown and described with reference to Figs. 1 to 5. In the operation of this form of the valve mechanism, the depression of the seat S, causes the simultaneous depression of the push button f thereby openmg the relief valve f" and causing the auxiliary valvef to seat itself on the seat e thus cutting off the communication between the inlet passage and the back pressure chamber. At the instant the relief valve is o en'ed, however, water in the back pressure c amber will be discharged through the bypass as reviously described and allowthe main va ve toopen to produce a flushing movement. When the seat S is released, it is raised by the spring-f, or other spring, permitting the auxiliary valve 1' to open.

. The relief valve j being already open, a second flushing occurs in the same inanrier'as before described... In this form of the valve it will, therefore, be seen that the bowl is flushed before and after the seat is depressed,

but the flushing is prevented while the seat is depressed, as the auxiliary valve cuts off the communication between the inlet passage and back pressure chamber, and also presses the main valve down onto its seat and\holds it'there. 5

Fig. 7 illustrates another slight modification of my invention which operates substantially as described with reference to Fig. oo

6, theonly difference being that the auxiliary valve, here lettered f is located on the stem of the relief valve, and engages a valve seat ft" on the opposite side of the relief ap-" erture from the re ular valve seat engaged by the valve j. Ihus when the seat is depressed the arm 8 will depress the push button and relief valve, opening therelief valve and producing a flushing of the bowl, until the auxiliary valve 1' closes, when the back pressure water accumulating in the back pressure chamber, will cause the main valve to close. When the seat is permitted to rise, a second flushing will-occur, the relief valve being open as soon as the auxiliary valve opens, and when the relief valve is closed by its springthe back pressure water will accumulate and close the main valve.

The forms of valve shown in Figs. 6 and 7 are particularly desirable for use in schools and certain other public buildings to insure a proper flushing of the closet. 7
